We also evaluate the effect of treatments on the political diversity of each participant's social networkNamely, their “followees” — i.e., who they follow on Twitter. 1, 2, and 3 weeks after use. In particular, we use Shannon's entropy similar to other studies exploring network connection diversity [1]}, [2]}, [3]} to quantify the balance of left and right-leaning accounts the user follows. Under this metric, user \(u\) 's diversity \(w\)  weeks after treatment, \(d_{u}^{w}\) , is given by:
\(d_{u}^{w} = - \sum _{l \in \mathbb {L}} p_l \log (p_l),\)
